(1) Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the
device is intended to be functional, but device parameter specifications may not be ensured. For ensured specifications and test
conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The maximum allowable power dissipation is a function of the maximum junction temperature, T
J
(MAX), the junction-to-ambient thermal
resistance, θ
JA
, and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated
using: P
D
(MAX) = (T
J(MAX)
− T
A
)/θ
JA
. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and
the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. Thermal
shutdown engages at T
J
=175°C (typ.) and disengages at T
J
=155°C (typ).
(4) Human Body Model, applicable std. JESD22-A114-C.

(1) All limits specified at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are
100% production tested. All limits at temperature extremes are ensured via correlation using standard Statistical Quality Control (SQC)
methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
